The factors of 63 are: 1, 3, 7, 9, 21, 63
The factors of 105 are: 1, 3, 5, 7, 15, 21, 35, 105
1, 3, 7, and 21
The GCF is 21.
The factors of 105 are 3,5, & 7. The factors of 63 are 3,3, & 7. One lot of '3' and one lot of '7' is common to both numbers. Hence 3 x 7 = 21 , which is the HCF of 105,& 63.
